The granted patent (Publication Number: US11998868B2) discloses a filter locking nut designed to securely engage with a threaded rod to fasten a filter element in place. The nut features an elongated body with receptacles at each end, including an internal thread at one end to engage the rod. The first receptacle has a rectangular opening with a circumferential groove to interact with an elongated tool, ensuring a secure connection during operation. When the threaded rod engages the second receptacle, the tool is disengaged from the groove, allowing for proper installation of the filter element.

Furthermore, the filter locking nut includes a cylindrical body with additional features such as a flange extending laterally and a wall defining a shoulder. The design of the nut allows for easy and efficient installation of filter elements, providing a secure locking mechanism to prevent any unwanted movement or disengagement during operation. Overall, the patented filter locking nut offers a practical solution for securely fastening filter elements in various applications, ensuring reliable performance and ease of use.
